Please add multiline tabs. I often have many tabs and it's much easier to navigate between them visually (i know where is each of them) then with dropdown or arrows.
Also, please add more descriptive names in document tab names, something like SQL1.SERVERNAME.DATABASE, or options with parameters so that everyone can name tabs based on connection. Now everything is SQL1, SQL2, SQL3 regardles on which database I'm connected to (and I'm usually connected to more that one database). Coloring helps me to distinguish between development and production database, but it's not easy do distinguish between two or more production databases (and I don't want to use different color for each database because I have lot's of them).
